Note 1: All characteristics are measured with a 0.1µF capacitor across the input and a 1µF capacitor across the output.
Note 2: Input regulation is expressed here as the percentage change in output voltage per 1V change at the input.
Note 3: Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible.
Thermal effects must be taken into account separately.
Note 4: Since long-term drift cannot be measured on the individual devices prior to shipment, this specification is not intended to
be a guarantee or warranty. It is an engineering estimate of the average drift to be expected from lot to lot.
